<p class="para1">Using sophisticated computer modelling, they found
these fast-moving stars, known as the Orion Nebula Cluster, were potentially
held together by the gravitational pull of a black hole
up to 200 times the mass of the Sun.
<br><br>
Formed one or two million years ago, the cluster has long been
known for its strange properties. Its stars move at a rapid speed,
as if the whole cluster was flying apart, reported the Astrophysical Journal.

Compared to the number of light-weight stars
that can be seen in the cluster, the number of heavy-weight
stars are too few and especially rapidly-moving, according to a Queensland statement.

"These properties have been a puzzle to astronomers,
given all the knowledge that they have about how stars
are formed and distributed," said Holger Baumgardt from the University of
Queensland's School of Mathematics and Physics, who co-authored the study.

"In our model, we had to invent a new method

out from the cluster by the intensely radiating
high-mass (heavy weight) stars," said Ladislav Subr,
of Charles University in Prague, who led the study.
<br><br>
Many of the heavy stars were sling-shot out of the cluster, while some were driven into the centre of the cluster and collided with the most massive star there.

At some point, this massive star became unstable and imploded into a black hole, with a mass about 200 times larger than the Sun.<br><br>"Our scenario neatly accounts for virtually all observed properties of the Orion Nebula Cluster, that is, its low number of high-mass stars, and its rapidly-moving central stars, and suggests that the massive stars
near the centre of this cluster are bound by a black hole," Subr said
